The one I went to a few years had Oliver V. showing retirees how to properly retrotrade. Then you have a few "market wizards" revealing their trading "secrets" that no longer work.

Well, if Ed Seykota showed up, I'd at least probably pay to hear him say "The elements of good trading are: #1 Cut your losses. #2 Cut your losses. #3 Cut your losses. If you can follow these three rules, you may have a chance. "
